DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 - Figure 5As shown, the utility model provides a technical solution: an intelligent electrical fire automatic extinguishing device, comprising an intelligent electrical cabinet 1, a wire management groove is provided on the left side of the intelligent electrical cabinet 1, a cabinet door 2 is rotatably connected to the front of the intelligent electrical cabinet 1, an automatic fire extinguishing mechanism 3 is arranged on the intelligent electrical cabinet 1, and the automatic fire extinguishing mechanism 3 comprises a limit card 31 and an arc-shaped plastic card seat, the limit card 31 is fixedly installed on the left side of the intelligent electrical cabinet 1, a sliding door panel 32 is slidably connected to the inner wall of the limit card 31, an extension seat 33 is welded on the outer wall of the sliding door panel 32, a connecting rope 34 is fixedly connected to the top of the sliding door panel 32, an end of the connecting rope 34 away from the sliding door panel 32 is fixedly connected to the right side of the inner wall of the intelligent electrical cabinet 1, and the middle part of the connecting rope 34 is fixedly connected to the inner cavity of the intelligent electrical cabinet 1. A low melting point fuse 35 and an arc-shaped plastic card holder are fixedly installed on the left side of the intelligent electrical cabinet 1. A gas cylinder 36 is movably inserted on the inner wall of the arc-shaped plastic card holder. The low melting point fuse 35 is an existing structural material and can be set to a lead-antimony alloy. After an electrical fire occurs, the temperature of the fire can cause the low melting point fuse 35 to melt, releasing the stretching positioning of the sliding door panel 32. The sliding door panel 32 and the expansion seat 33 then slide down to apply pressure to the pressure-starting valve tube 363, causing the carbon dioxide accumulated in the gas cylinder 36 to be transported to the inner cavity of the intelligent electrical cabinet 1, and the oxygen inside the intelligent electrical cabinet 1 is replaced from the gap of the intelligent electrical cabinet 1, thereby realizing the function of extinguishing the electrical equipment inside the intelligent electrical cabinet 1. In the event of natural damage or power outage of the fire protection system, automatic fire extinguishing can still be performed.

[0023] As an implementation method in this embodiment, Figure 1 - Figure 5As shown, the output end of the air storage cylinder 36 is detachably connected to a connecting air pipe 361, and the end of the connecting air pipe 361 away from the air storage cylinder 36 is fixedly connected to a three-way pipe 362, and the right side of the three-way pipe 362 is fixedly connected to a pressure-activated valve pipe 363, and the right side of the pressure-activated valve pipe 363 is fixedly connected to the left side of the intelligent electrical cabinet 1, and an inner partition 364 is fixedly installed on the inner wall of the pressure-activated valve pipe 363, and a sealing plate 365 is movably connected to the inner wall of the inner partition 364, and a lower pressure shaft 368 is fixedly connected to the top of the sealing plate 365, and the top of the lower pressure shaft 368 extends to the top of the pressure-activated valve pipe 363, and the outer wall of the lower pressure shaft 368 is connected to the pressure-activated valve pipe The inner wall of 363 is slidably connected, and the bottom of the sealing plate 365 is fixedly connected with an elastic member 366. The bottom of the elastic member 366 is fixedly connected to the bottom of the inner wall of the pressure-starting valve tube 363. The top of the inner partition 364 is fixedly installed with a limit block 367 located in the inner cavity of the pressure-starting valve tube 363. The bottom of the limit block 367 is movably connected to the top of the sealing plate 365. After the sliding door panel 32 and the expansion seat 33 slide down, the downward pressure shaft 368 can be pressed down to cause the sealing plate 365 to move downward, so that a gap is generated between the sealing plate 365 and the inner partition 364. Through this gap, the carbon dioxide inside the gas storage cylinder 36 can be discharged into the inner cavity of the intelligent electrical cabinet 1.

[0024] As an implementation method in this embodiment, Figure 4 As shown, the automatic fire extinguishing mechanism 3 also includes a support member 351 and an arc detector 353. The support member 351 is fixedly installed on the right side of the inner wall of the intelligent electrical cabinet 1. A heating rod 352 is fixedly installed between the adjacent sides of the two support members 351. The arc detector 353 is fixedly installed on the right side of the inner wall of the intelligent electrical cabinet 1. The arc detector 353 is connected to the heating rod 352 through an electrical signal between an external controller. The arc detector 353 is an existing structural model and can be selected as ZY-AFD. Through the design of the arc detector 353, whether an electrical fire occurs inside the intelligent electrical cabinet 1 can be monitored. If a fire is detected, the heating rod 352 is controlled to work through the external controller, and the low-melting-point fuse 35 is heated to cause the low-melting-point fuse 35 to melt, thereby realizing the function of rapid fire extinguishing.

[0025] Working principle: When in use, the arc detector 353 is used to monitor whether an electrical fire occurs inside the intelligent electrical cabinet 1. If a fire is detected, the electric heating rod 352 is controlled to perform heating, causing the low-melting-point fuse 35 to melt, and the stretching positioning of the sliding door panel 32 is released. The sliding door panel 32 and the expansion seat 33 then slide down to apply pressure to the pressure-starting valve tube 363, causing the carbon dioxide accumulated in the gas cylinder 36 to be transported to the inner cavity of the intelligent electrical cabinet 1, thereby extinguishing the fire of the electrical equipment inside the intelligent electrical cabinet 1. If the arc detector 353 and the electric heating rod 352 are naturally damaged, the temperature of the fire can also cause the low-melting-point fuse 35 to melt, thereby achieving the fire extinguishing function.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
